问题
I am trying to pass my session variables to my handlebars templates but am getting stuck. Right now I am using this in my app.configure function:
app.use(function(req, res, next){
res.locals.session = req.session;
console.log(res.locals.session);
next();
});
It logs correctly to the console, but when I try to use the "session" variable in my handlebars template, nothing shows up. Here is part of my template:
<body>
<nav>
{{> topBarPartial}}
{{> secondaryBarPartial}}
</nav>
<div>
<p>before</p>
{{session}}
<p>after</p>
{{> mainPartial}}
</div>
{{> footerPartial}}
</body>
Here is what is being logged by the console:
{ cookie:
{ path: '/',
_expires: null,
originalMaxAge: null,
httpOnly: true },
userId: 45253262,
name: 'Austin' }
Any ideas?

I finally found my solution. It turns out that I was calling this:
app.use(function(req, res, next){
res.locals.session = req.session;
console.log(res.locals.session);
next();
});
after
app.use(app.router);
It actually needs to be before the app.router, but after
app.use(express.session({
secret: '***********'
}));
